I would go for the shower! Install what is of value to you since you're living in such a nice home. We have a shower in our little mast bath and I wouldn't trade it for a bath tub.: we are in a perfect little house for the aging retirees, except its' one bathroom needs either a new tub and tile job, relining existing one, or replace tub with shower unit and gain storage space. Advise please. Hoa much value would be lost if we go with shower unit instead of tub and tile replacement?
